ok i see the problem,your in one them mixs that you dont know which way to feed,half peat moss,that feeding would be 6.5ph,the coco would be 6 ,so your 50/40 mix kinda leaves you in limbo of which way to goon feeding,so im out i havent quite understood why they do this mix in first place,mt thought,50.40 peat moss /perlite,ot 50/40 coco perlite,at the least you know how to feed,i sure wouldnt feed dry amends if you are,your looking for a train wreck,that joker on you tube might have a grand worth experience using the dry stuff,but it is not for the newbie.
when you feed dry amends you scratch it into the top of your soil,which you dont have or do you see what i mean,when you scratch it in you just water over it and nutes go down,that works just great for veggies in the outdoors
im visiting 4 difrent forums daily and every one that try dry amends in soil or coco or perlite for that matter flood the forums with help me threads.
i love
fox farm soil,but the worst shit they have is that coco loco crap,sorry just telling the truth,but i suggest you feed by the hannah feed schedule as in ec/ppm counts to the T and as far as your ph ,i have gone as high as 6.2 in coco and 6.8 in soil and struggled threw a run ,so that one is in your court mate,sorry couldnt help
